A method of coating a component of an electrolyser is provided. The method comprises applying an acidic solution of platinum cations to at least a portion of the component and reducing the applied platinum cations with a reducing agent to form a layer of platinum metal on the component.

The present invention relates to a process for the preparation of alkoxylated 2.5-dihydrofuran. The process is carried out in an electrochemical cell reactor with a vertical flow.

An electrolyzer that includes an anode configured for being connected to a first pole of a voltage source; a cathode configured for being connected to a second pole of the voltage source; a fluid inlet configured to allow a flow of fluid to enter the electrolyzer; and a fluid outlet configured to allow the flow to exit the electrolyzer, wherein the electrolyzer is configured to cause the flow to have a flow speed profile along a flow axis with a relatively higher flow speed at the flow axis between the anode and the cathode, wherein the flow speed becomes relatively lower at locations away from the flow axis and more proximate the anode and the cathode, and wherein the electrolyzer has an entrance length that causes the flow speed profile to be at least a partially developed laminar flow when the flow reaches the anode or the cathode.

A system (1) for generating hydrogen gas comprises a reaction vessel (101) containing an aqueous solution (102) and a cathode (105) and an anode (107) each positioned at least partly in the reaction vessel (101). The system (1) comprises first and second ultrasonic transducers (215-220) which emit ultrasonic waves in the direction of the cathode (105) and the anode (107) respectively. Each ultrasonic transducer (215-220) is driven by a respective transducer driver (202) to optimise the operation of the system (1) for generating hydrogen gas by sonoelectrolysis.

An electrolytic liquid generation device includes a stacked body in which a conductive membrane is stacked and interposed between a cathode and an anode adjacent to each other, an electrolytic part that electrolyzes a liquid, and a housing in which the electrolytic part is disposed and a flow path is formed. The electrolytic part includes a slot that is open in the flow path, and in the slot, a part of an interface between the conductive membrane and the cathode and the anode is exposed. Either one of the electrodes of the cathode and the anode has an outer periphery smaller in width than the slot of the electrolytic part. This can provide an electrolytic liquid generation device capable of improving the concentration of an electrolytic product dissolved in the liquid.
